Final answer:
The merchant uses 60 pounds of tea that sells for $4.75 per pound and 50 pounds of tea that sells for $2.50 per pound in the blend.
Step-by-step explanation:
To solve this problem, we can set up a system of equations.
Let's say the merchant uses x pounds of tea that sells for $4.75 per pound, and y pounds of tea that sells for $2.50 per pound.
We can use the information given to set up the following equations:
- x + y = 110 (equation 1, representing the total weight of the mixture)
- (4.75x + 2.50y) / 110 = 3.85 (equation 2, representing the average price per pound of the mixture)
We can solve this system of equations to find the values of x and y.
From equation 1, we can isolate x to get x = 110 - y.
Substituting this into equation 2, we get (4.75(110 - y) + 2.50y) / 110 = 3.85.
Simplifying and solving for y, we find y = 50.
Substituting this value into x = 110 - y, we find x = 60.
Therefore, the merchant uses 60 pounds of tea that sells for $4.75 per pound and 50 pounds of tea that sells for $2.50 per pound in the blend.
